Lumbar vertebra bone. Cross-section through a gross specimen of a lumbar (lower spine) vertebra. The inner bone is called spongy,or cancellous,bone. It is characterised by a honeycomb arrangement,comprising a network of trabeculae (lattice-like tissue). These structures provide support and strength to the bone,whilst being lightweight. The spaces within the tissue contain bone marrow,a blood forming substance,that has been lost as this specimen was dried. The perimeter of the bone is made from thicker bone called compact,or cortical,bone | |
